Be it lrnown that I, HENRY A. BENNETT, a citizen of the United States,residing at Aurora, in the county or" Kane and State of 5 Illinois, haveinvented railway, passenger object of the inven versible lever strucembodies, in combinat provements in Levers, of which the following is aspecification.

This invention relates to lever constructions which are principallydesigned for use in applying brakes on various types of street orfreight cars, and an tion is to provide a ture as specified which lever,a double pawl holding the lev either ings, the i therefrom as is o ofapplying bra for engagement with an internal ratchet for or in.adjusted. positions and consequently holding a brake in adjusted appliedor unapplied positions. Other objects of the invention will appear inthe following detailed description taken in connection with the drawingswherein:

Any tendency of the link23 to move the tab 22 down. wardly will jam the point 19 into ment withthe teeth thereby locking the parts. Inother words the point 19 acts asa fulcrum engagessure against the pin rts. In the winding shaft 1t 1s,or course,

to be understood that the links 8 and 23 will wrap around the shaft B.

In Fig. 2 of the drawings a hand wheel 2% is shown mounted upon the rodB and it is this hand wheel may l? by a' trans he employed if desiredWithout departing from the spirit of this invention.

It is, of course, to be understood that the ins tion may be constructedin other manparts associated in other relations and, therefore, I do notdesire to be limited in any manner except as set forth in the claimshereunto appended.

Having thus described my invention What I claim is: 1. In a device asset forth, an operating rod, a lever, a pawl carried by said lever, saidpawl and lever provided with registering slots receiving therethroughsaid rod, said pawl provided with opposed operating tips, and a doubletoothed internal ratchet cooperating with said. pawl.

2. In a device as set forth, an operating rod, a lever, a pawl carriedby said lever, said. pawl and lever provided with registering slotsreceiving" therethrough said rod. said pawl provided with opposedoperating tips, a double toothed internal ratchet cooperating with saidpawl, connecting members connected to said rod upon opposite sides ofsaid pawl, and links pivotally connected to said connector members.

3. In a device as set forth, a lever, a pawl attached thereto. said pawland lever provided with registering slots, an operating :taeeyat rodextending through said slots, said pawl and lever movable relative tothe rod with: in, the limits of said slots and adapted to rotate the rodupon further movement of the lever, an internal double toothed ratchetmounted about said rod, said lever movable to inc ".0 said pawl intocooperation with said ratchet at opposite sides of the rod.

l. In a device as set forth, a lever, a pawl attached thereto, said pawland lever provided with registering slots, an operating rod extendingthrough said slots, said pawl and lover movable relative to the rodwithin the. limits oi said slots and adapted to rotate the rod uponfurther movement of the lever, an internal double toothed ratchetmounted ahout said rod, said lever movable to H1031, said pawl intocooperation with said ratchet at opposite sides oi the rod, andconnecting members attached to said rod upon opposite sides of said pawland rod, and links pivot ally connected to said connecting members.
